I dunno man it did take quite a while to get up there, but it was (ironically to be sai d in this topic) downhill that I did this, so it helped a LOT. I don't even remember if it was 135 exactly it could have been 135-145 I don't relaly remember what it says I jsut remember freaking the fuck out when I looke dup and passed a hidden cop, and that I somehow got out of a ticket. I haven't gone over 90 since then.

but still (more on topic) if the speedo error IS %10 then it's still possible that his speedo read 160, and someone said his tire size might affect the read out also, so it may very well have read that, whetehre he was actually going that speed or not is another story, btu I'm saying it's perfectly possible to have the speedo read 160 mph.

 

160 in a cl-s ? NOW thats just BULLSHIT in a normal cl, the max ive gone is 138 mph over a wide course of LONG rode. YOUR cls gearing isnt even able to produce those numbers

 

Actually it is. 147 is possible in 4th gear. Top speed is limited by the electrontic limiter.

Now if he got to 160 or not is another debate, but based upon the FACTS produced by EricL it is possible given ideal conditions. That is, if the limiter is disabled.

 

maybe there was a tail wind too... lol

 

I don't think you can get past 150... my max was around 145-147ish and it took a while to get there and I got i/H and was a cold night out...but stock? What would John Stosell say? Gimme a break! Hahaha.

 

Astroboy showed pictures of his Type-S hitting 147 (I'm not going to get into the speedo error argument). The magazines have shown the top-speed data. I don't see what the problem is with a well-supported figures. (Heck, this info has been around for 3+ years...)


The CLS can definitely do 160+ MPH when tossed out the back of a C5A Galaxy (you can leave the limiter in ). Not sure the driver and/or passenger would consider that "ideal conditions."

Also, quite amazing what a tail wind will do.

Following discussion is based on NO TOP SPEED LIMITER:
Considering that the bulk of the aerodynamic drag is related to V^2, having a sizeable tailwind + no limiter can make for very high top speeds on rare occasions. And, conversely, having a strong headwind, a slight uphill grade, combined with some heat and attitude, can make for a very slow climb to even 120 MPH.

More than a few F1 teams have been caught with their pants down when they selected their gearing for Monza and other high speed tracks, only to find that wind, temperature and other "unpredictable" behavior didn't behave as "planned"/”simulated” on race day.

 

It takes a long, long stretch of road to reach terminal velocity on a flat road with "clean air." This presumes that the car's top speed is NOT limited by gearing (hitting the rev limiter in the highest gear), or running into the top-speed limiter.


Again, if you didn't have the top-speed limiter (an important detail) *and* if you had a 10-mph tail wind, you could easily hit 150 with the car dead stock.


Hell, the car could probably do 657,205,944 mph (approx 0.98 * C) in space with enough time and a small ion motor with a few lbs of thrust...

 

is there anyone with there limiter disabled???

i wonder what we can hit w/o one, cause were still in 4th at 147mph

 

wow, a super-optimistic speedo.

 

Yeah, less tickets. Just set the speedo to equal 100 when going 60. Some poor driver who wasn't clued-in might get a few scratches and honks tho....

 

i got struck by lighting three times this weekend.... i believe he hit 160 while in vegas. . . .


J/k.....

 

dude, you know too much!

 

ok.. so it read 160... so make it read 160 again and then take a picture of it.. :gheyfight:

 

you guys can produce all these details and mathematical calculations till youre blue in the face....it doesnt matter, the guy is full of shit....whether or not its THEORETICALLY possible doesnt matter....the CL-S has a speed limiter....period. the only way to get the car to go beyond that speed limiter is to disable it somehow, or to find a way to apply forward momentum other than with the engine of the car...and even then, there arent many possiblities, youd have to be doing 147 (speed limiter cut off) and then somehow get the car to go another 13 mph faster....so youd have to be doing 146 (fastest you can go before the speed limiter activates) and then have a gale force wind behind you and going downhill in order to pick up the extra needed speed to get to 160.

this is just bullshit, period.

 

maybe he tried this at an airport, faced an airplane on the ground back to back, and when they both took off, the force of the airplane engine gave him a back wind to push him to that speed.

 

The airplane was probably towing him

 

he was going from VEGAS to ARIZONA

 

If it did it once, it will at least get cose to doing it again. And if it does, you will probably get positive rep from everybody.

 

:captainobvious:

 

i dont know about yours, but if my cl-s ever hit 160mph, i think the car would fall apart along with the transmission taking a major dump about 3 miles back..

 

Well, time to eat crow. I talked to the guy and he is an engineering genius. He rigged-up a re-calibrated speedo and added planetary drive units at the output of each half shaft. What a piece of engineering. High-strength magnets combined with a regenerative braking system, electric motor assist, and 42-volt electronics located in the trunks supply's an extra 200 HP through the planetary gears/direct assist electric motors -- this completely isolates the rev-limiter and allows for a radar-verified 188 MPH (190 one direction, and 186 in the other).

The speedo has been re-calibrated to compensate for the change in final gearing.

Sorry you couldn't have been there Jim it was really interesting to see.

I'm sending everyone a copy of math calc. commentary and we've all agreed to move to an Amish community and give up science and technology.

 

Eric, you rock.
